Slippery roadIreland
23. Slippery road
A slippery road has reduced tyre grip and can make steering, braking and acceleration less effective. Roads may become slippery because of rain, ice, snow, mud, oil, loose material or other substances on the surface. Drivers should reduce speed, increase their following distance and avoid sudden steering, braking or acceleration. Extra caution is needed in bends, on bridges and wherever the road surface changes unexpectedly.

What can make roads slippery in Ireland?
Be prepared for rain, wet leaves and occasional frost or ice. A surface can become slippery even if it looks clear, and different parts of the road may have very different grip.

How should you drive on a slippery road in Ireland?
Reduce speed early, increase the gap to the vehicle ahead and use smooth steering, braking and acceleration. Do not rely on the posted maximum as a safe target when grip is poor.

Does a slippery-road warning sign in Ireland automatically impose a lower number?
The warning sign highlights a reduced-grip risk; it normally does not itself prescribe a new numerical speed limit. A separate speed-limit sign, temporary restriction or local condition may still apply. Travel below the legal maximum when necessary for safety.
